| Amendment Description | EXPLANATORY NOTE Akumin Inc. is filing this Amendment No. 1 to the Annual Report on Form 10-K/A (“Amendment No. 1”) to amend its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 as filed with the Securities and Exchange Commission (SEC) on March 16, 2022 (the “Original Filing”). The principal purpose of this Amendment No. 1 is to include the Part III information that was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K. Because no financial statements are contained within this Amendment No. 1, the Company is not including the individual certification pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 regarding financial statements, disclosure control procedures, or internal controls over financial reporting. Additionally, because no financial statements are contained within this Amendment No. 1, the Company is not required to file the certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. No attempt has been made in this Amendment No. 1 to modify or update the other disclosures presented in the Original Filing. This Amendment No. 1 does not reflect events occurring after the Original Filing or modify or update those disclosures that may be affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and our other filings with the SEC. In this report, unless otherwise stated or as the context otherwise requires, references to “Akumin,” “our company,” “we,” “us,” “our” and similar references refer to Akumin Inc. and its subsidiaries. |
